Introduction The Bear River Watershed Comprehensive Lake
Management Plan includes sections for each of the
ten lakes in the watershed. The lakes are in the
largest watershed in Lac du Flambeau, within the
Reservation’s boundaries, associated with high use
landings, and have complete data sets required for a
lake management plan. The purpose of the plan is to
establish the current health of the watershed and
lakes and suggest how to maintain or improve their
health in the future.
This section includes introductory information about
White Sand Lake; a summary of how uses of the
lake have changed over time; data from the
community survey; and an assessment of the lake’s
health based on data for the lake’s biology,
chemistry, nutrients, habitat, bacteria, lake levels,
and aesthetics. This section also includes an action
plan for improving or maintaining the overall health
of White Sand Lake.
White Sand Lake is in the Bear River Watershed
(Subwatershed HUC12-070500020202) northeast of
the town center of Lac du Flambeau (Figure 21-1).
Figure 21-1. Map of Lakes
The lake is approximately 1229 acres and has a
maximum depth of 63 feet (Table 21-1). White Sand
Lake is classified as a drainage lake, meaning that it
is fed by streams, groundwater, precipitation, and
run off, and is drained by a stream or channel. White
Sand Lake drains through Hutton’s Creek at its
western end into Pokegama Lake where it ultimately
flows into the Bear River.
From the northeast shore of this lake (Pokegama
Lake), a portage of half a mile, over sand hills,
covered with small pines and elevated about thirty
feet above the general level of the small lakes which
leads to Lake Wepetangok (White Sands Lake).

Tourism did not employ as many people as
lumbering in its heyday, but it did mix traditional
and modern subsistence practices and fit within a
regional tradition of seasonal work.

White Sand Lake stratifies annually with the
hypolimnion reaching dissolved oxygen below
5mg/L. With Secchi readings averaging 15.24 feet,
the lake’s water clarity is considered to be good.
Based on Secchi, total phosphorus, and Chlorophyll
a data, White Sand Lake is classified as
mesotrophic. Mesotrophic lakes generally have
medium levels of nutrients and water clarity when
compared to other natural lakes.
White Sand Lake’s watershed includes water
(44.7%), forests (44%), urban (0.3%), and wetlands
(11%).
There are 202 dwellings, mostly residential, within
300 feet of the lake’s shoreline.
White Sand Lake has a public landing off of County
Road H and two private landings, one at each of two
resorts and another one at the private campground.
Brief History of White Sand Lake The history of White Sand Lake, including how uses
of the lake have changed over time, parallels the
history of the other lakes in the Bear River
Watershed as described at length in Section 3.
Unless noted otherwise, the information here is
footnoted in Section 3.
For hundreds of years White Sand Lake was used
by indigenous people for subsistence. Virtually every
facet of their lives depended on their relationship
with the lake and its surrounding habitats for food,
medicine, building materials, and transportation.
With the arrival of the Europeans in the early to mid-
seventeenth century, White Sand Lake and the
surrounding habitats took on a new use: to help
provide the world with furs. Lac du Flambeau
became a transportation center for the fur trade, and
White Sand Lake became part of the network of
canoe routes and portages which linked Lac du
Flambeau with trade routes in all directions. White
Sand Lake, for example, was part of the primary
route linking Lac du Flambeau with Lac Vieux Desert
to the northeast.4
By 1840 the fur-bearing animals were gone and White
Sand Lake and its surrounding habitats took on
another new use: to provide the country with timber
and timber products. To facilitate the movement of
logs from White Sand Lake to the mills on Long
Interlaken Lake, a dam was constructed at the
confluence of Flambeau Lake and the Bear River.
Hutton’s Creek (Sand Creek) connects White Sand
Lake at its southwest end with Pokegama Lake. The
dam there was likely built originally by the Tribe in
the mid-1870s. When property on White Sand Lake
was subsequently sold, the creek and dam
Section 21: About White Sand Lake 21-3
Bear River Watershed Comprehensive Lake Management Plan
transferred to private ownership. In 1940, the Town
of Lac du Flambeau paid August Wolff $135 to
replace the original dam which had washed out.5
In the 1900s, Marvin Hewitt, the president of the
Chicago and Northwestern Railroad, decided he
wanted to take his steam launch with his guests
fishing in more than one lake. Railroad construction
crews dug about four miles of ten-foot wide canals to
link White Sand, Sunfish, Crooked, Little Trout, and
Ike Walton Lakes.6
By 1913, the trees around White Sand Lake were
gone and most of the surrounding habitats were
destroyed. In the early 1900’s, however, the logging
industry was already being replaced by the service
industry, which used White Sand Lake and its
surrounding habitats to meet the recreational needs
and demands of tourists and seasonal residents.
As a result of the Dawes Act (1887), much of the
lakefront property on White Sand Lake was
transferred from the Tribe to non-Tribal residents,
opening the door shoreline to development.
In 1910, George Goller built the first tourist cabins
on White Sand Lake.7 In 1923 Gust Peterson and his
two brothers, Fred and Oscar, bought the 35-acre
peninsula and the property to the east and west as a
retreat center for their families.8
Later that year, Gust Peterson sold his 35 acres on
the peninsula on a land contract to his nephew Ben
C. Gauthier, who constructed a hotel and 13
buildings on the 35 acre site and began work in the
resort business.9
Dillman’s Resort was born in 1934 when Marvin and
Peg Peterson Dillman purchased the same 35-acre
property on a land contract from Peg’s father, Gust
Peterson (Figure 21-2). In order to help keep the
resort, Marvin and Peg tried raising chickens, mink,
and milk cows plus held winter jobs in Chicago. In
1970 the present owners, Sue (Marvin and Peg’s
daughter) and Denny Robertson, took over
managing the resort.10
Figure 21-2. Dillman’s Resort on White Sand Lake
One of the cabins on the property today sheltered
Baby Face Nelson who was on the run in April 1934
following a shootout at Little Bohemia in Manitowish
Waters. At the time Baby Face Nelson used the
cabin, it was the home of Ollie Catfish and was
located across the lake from Dillman’s. In 1935, Peg
and Marvin Dillman moved the then empty building
across the frozen lake for use as a cabin for their
patrons.11
In 1923, a second of the Peterson brothers, Oscar,
opened a small resort west of his brother Gust’s
property. Eventually he sold the resort to Joyce and
Bob Watson who ran Watson’s Holiday Beach
Resort for 25 years. The third Peterson brother,
Fred, also sold his property, which eventually
became the present White Sand Resort.12
In the 1930s, Molly and Mitch Bloecher established
Bloecher’s Beach Resort near Dillman’s Resort.
Laurie and Rick Zelm purchased Bloecher’s Beach
Resort in 1986 and renamed it White Sand Resort.
Timber Bay Resort, formally, Watson’s Holiday Beach
Resort is now owned by Sean & Darcy McEnroe.13
In 1922, 11 families from Winnetka, Illinois
purchased 90 acres with frontage on both White
Sand and Little Sand Lakes for a private camp. They
called it Camp Wipigaki, Ojibwe for Red-at-the-Leaf.
By 1925 Wipigaki had grown to 500 acres and had
cabins and a common dining hall.14

Bear River Watershed Comprehensive Lake Management Plan
By the 1960s, tourists could choose among several
resorts on White Sand Lake, including Anderson’s
Resort, Field’s Log Cabin Resort, Schmidt’s
Breezewood Resort, Watson’s Holiday Beach, and
Dillman’s Sand Lake Lodge.15
Presently there are
three resorts on White Sand Lake, Dillman’s Resort,
Timber Bay Resort, and White Sand Resort.
Community Survey16
Approximately 3,000 households in Lac du
Flambeau were invited to participate in a mail survey
during the summer of 2012 to provide information for
preparing the Bear River Watershed Comprehensive
Lake Management Plan. The survey was developed
with assistance from the Wisconsin Department of
Natural Resources and was approved by the WDNR
before it was distributed.
The survey includes questions on topics such as
residents’ perceptions of the quality of lake water,
fishery, and overall environment; residents’ familiarity
with aquatic invasive species and aquatic plants;
residents’ perceptions of current and ideal shoreline
landscaping; and residents’ interests in a variety of
workshops. The survey, data tables, and other
information related to the survey are in the appendix.
One-third of the questionnaires (996) were returned
completed, representing 51 lakes. Of the returned
questionnaires, 576 (58%) provide information on
the ten lakes in the Bear River watershed and of
these, 102 (18%) focus on White Sand Lake.
Tables showing results of the survey are presented
throughout the rest of this section. Care should be
taken when interpreting the survey data because in
many cases the number of respondents for White
Sand Lake is very low.
Assessing Lake Health Medical doctors assess human health by examining
a patient’s blood work, height, weight among
numerous other measures (quantitative data) and by
considering information like the patient’s answers to
questions, comments, even body language
(qualitative data). Similarly, lake managers assess
lake health by examining the lake’s oxygen,
nitrogen, phosphorus, among other measures
(quantitative data) and by considering additional
information about the lake like the presence of
aquatic invasive species, nuisance aquatic plants, or
even presence of trash (qualitative data).
White Sand Lake Health Report Assessing the health of White Sand Lake has
included examining qualitative and quantitative data
pertinent to the lake’s biology, chemistry, nutrients,
habitat, bacteria, aesthetics, and fish tissue. These
categories are introduced in the next few pages and
are addressed at length in the rest of the section.
Table 21-2 shows the categories, their subdivisions
(Indicator Assessments), and the ratings that have
been applied to them, Excellent, Good, Fair, Poor,
Concern or Not Assessed (See Section 10 for
details on rating).
The Biology Category reflects an assessment of the
number and magnitude of invasive species. White
Sand Lake has rusty crayfish, freshwater jellyfish,
and purple loosestrife, but none at the nuisance
level. Other than purple loosestrife, the lake does
not have any invasive plants.17
The floristic quality
index18
is good (FQI 34.5), and the lake's overall
status for the Biology Category is good.
The Chemistry Category reflects an assessment19
of
data for dissolved oxygen, pH, temperature, ionic
strength, and suspended solids as compared to
water quality standards criteria.20
Dissolved oxygen
for White Sand Lake during the summer can reach
below 5mg/L, the criteria for cool water fish, so it has
a status of good. White Sand Lake’s overall status
for the Chemistry Category is excellent.

compared to National Lake Survey (NLS)
thresholds22
for the upper Midwest ecoregion health
conditions and for the upper limit compared to
Wisconsin’s new water quality standards for a two-
story fishery lake.23
The NLS was a study of Lakes
across the United States, and thresholds for good,
fair and poor were developed based on the data
collected for each ecoregion. White Sand Lake’s
overall status for the Nutrients Category is excellent
as average total phosphorus is 11.20µg/L, and
Chlorophyll a is 3.1µg/L.
The Habitat Category reflects an assessment24
of
White Sand Lake’s aquatic plants, riparian zone
(shoreline), and littoral zone (shallow water along
shoreline). Comparisons are made with ecoregional
data and National Lake Survey thresholds.25
All
indicators for White Sand Lake have a rating of
good. White Sand Lake’s overall status for the
Habitat Category is good.
The Bacteria Category reflects an assessment26
of
summer E. coli measurements that were taken
weekly and then compared to Water Quality
Standards criteria27
for human health protection.
White Sand Lake does not have a public beach so
the lake was not assessed for bacteria.
The Aesthetics Category reflects an assessment of
data and information on water quality, color, and
turbidity as well as an assessment of reports
received by the Tribal Natural Resources
Department for White Sand Lake on the presence of
oil, grease, nuisance aquatic plants, and
trash/debris. This information is compared to
narrative criteria as described in the Water Quality
Standards.28
White Sand Lake’s overall status for
the Aesthetics Category is excellent.
The Tissue Category reflects an assessment of the
amount of mercury in the flesh of fish in White Sand
Lake as compared to the Water Quality Standards.29
Larger edible fish have more mercury in their flesh
than what is protective for human health concerns.
White Sand Lake’s overall status for the Tissue
Category is of concern.
The lake levels were assessed for White Sand Lake
but a condition criteria has not been developed at
this time. Information about lake levels is presented
at the end of this section.
Biology Category Biology is the science of living organisms. The
organisms that live together in the lake interact in
large part based on their food relationships. The
food pyramid for lakes (Figure 21-3) shows the
proportion of biological production to the yield of
large fish. The organisms are in balance after
thousands of years of naturally evolving together
within these food relationships.
21-6 Section 21: About White Sand Lake
Bear River Watershed Comprehensive Lake Management Plan
Invasive species, however, are organisms that
evolved originally in other locations and when they
move into a naturally balanced area disrupt the
native organisms’ relationships.
Figure 21-3. Lake Food Pyramid
Invasive species are a great concern. Their
introduction can cause changes of native organisms’
distribution and abundance and contribute to water
quality degradation. The introduction of the invasive
aquatic plant, Eurasian water milfoil, can cause the
reduction in large game fish as the native insects
and small fish have not evolved to eat EWM,
causing a loss of food resource for large fish and an
overabundance of plant matter.
White Sand Lake has rusty crayfish, freshwater
jellyfish, and purple loosestrife (see Section 7 for
specifics). At this time, however, there is no
evidence that they are disturbing the abundance or
distribution of native organisms or causing economic
or ecological harm.
To help determine the extent of residents’ familiarity
with Aquatic Invasive Species (AIS), the community
survey asked residents to answer a few questions
about AIS. Their responses to some of the questions
follow.
Residents were asked if they had heard of AIS
before reading about them in the survey. For White
Sand Lake, 34 of 102 respondents (33%) indicate
they had prior knowledge of AIS as compared to 171
of 576 (30%) for respondents of the ten lakes in the
Bear Watershed, and 300 of 996 (30%) for all
respondents from Lac du Flambeau.
Residents having prior knowledge of AIS were
shown a list of AIS and then asked which, if any, are
currently in the lake. Table 21-3 shows the
responses of 34 residents for White Sand Lake. The
table also shows whether the AIS are actually in the
lake. For example, 3 of the 34 residents believe that
Eurasian water milfoil is in the lake, when in fact it is
not. The table shows there is a general
disconnection between residents’ perceptions of the
presence of AIS and the actual presence of AIS.
Table 21-3. White Sand Lake - Perceived vs Actual Presence of AIS

Banded Mystery Snail 2 of 34 6% No

The same 34 respondents were asked to identify
what they believe is threatened by AIS. Table 21-4
summarizes the responses for White Sand Lake, the
ten lakes in the Bear River Watershed, and the 51
lakes in the survey. The largest percentages of
responses for all three groups of respondent’s show
that native fish, aquatic plants, and water quality are
most threatened. The lowest percentage of responses
for all three groups of respondents is for air quality.

The same residents were also asked if they are
concerned about AIS getting into the lake. Table
21-5 shows that for 34 respondents for White Sand
Lake, 48% indicate extremely concerned, 39%
somewhat concerned, 7% not too concerned, 0%
not concerned at all, and 7% unsure. Data for all
three reference groups shows respondents have
great concern about AIS getting into the lakes.

shows that for 32 respondents affiliated with White
Sand Lake, 38% indicate not at all, 34% once a
season, 22% monthly, 6% weekly, and 0% daily.
The data for White Sand Lake is similar to the data
for the other lakes and shows that despite concern
for AIS, very few residents indicate they spend time
looking for AIS regularly.

Chemistry Category Chemistry is the science of matter and its properties
and composition with a particular focus on the
properties of chemical bonds. Dissolved oxygen, pH,
temperature, ionic strength, and suspended solids
each have a particular role in chemical bonding and
movement of chemicals within the lake.
Seasonal changes and water temperature of the
lake have an impact on the amount of dissolved
oxygen in the lake, important for fish respiration and
viability (see Section 9, Understanding Lake Data).
Dissolved oxygen in White Sand Lake during the
summer and late winter can reach below 5mg/L, the
minimum criteria for cool water fish (Figure 21-4).
Lake whitefish (Coregonus elupeaformis), for
example, is a cool water fish that is very susceptible
to temperature and dissolved oxygen. White Sand
Lake has had occasional die-offs of whitefish in the
shallow parts of the lake where the fish were
confined.
21-8 Section 21: About White Sand Lake
Bear River Watershed Comprehensive Lake Management Plan
Figure 21-4. Dissolved Oxygen and Temperature Values for White Sand Lake at Various Depths
Calcium for White Sand Lake as measured in 1990
was on average 3 mg/L, quite low, meaning White
Sand may be less susceptible to infestations of
Zebra Mussels.
Nutrients Category Based on Secchi, total phosphorus, and chlorophyll
data, White Sand Lake’s trophic state is
mesotrophic, meaning it has medium amounts of
nutrients to support a productive food web. A
productive food web includes a diversity of rooted
plants, macro-invertebrates (insects), and healthy
fish populations.
Phosphorus and nitrogen are two nutrients that play
key roles in limiting the growth of aquatic plants and
algae (see Section 9, Understanding Lake Data). Of
these, phosphorus is most critical to White Sand Lake.
Phosphorus originates from sources like human and
animal wastes, soil erosion, detergents, septic
systems and runoff from lawns. Phosphorus is the
limiting nutrient for White Sand Lake, meaning that
when the amount of phosphorus increases, the
probability of algae growth also increases. Total
phosphorus between 10 and 18ug/L is associated
with mesotrophic lakes and medium production of
biomass (Figure 21-5).
Figure 21-5. Total Phosphorus Concentration Trends in White Sand Lake
As the amount of algae increases, it is likely that the
amount of chlorophyll a increases. Chlorophyll a is a
green pigment present in all plant life and is
necessary for photosynthesis. The amount of
Chlorophyll a is a common measure of water quality
(Figure 21-6).
Figure 21-6. Chlorophyll a Concentration Trends in White Sand Lake
Figure 21-7 shows Secchi depth, total phosphorus,
and Chlorophyll a trends for White Sand Lake from
1979 until present. No significant change in water
quality is noted over this time period.
White Sand Lake's shoreline includes primarily
seasonal residences and properties. Though the
lake's shoreline has been almost completely
developed, the watershed overall remains forested.
More growth and development are expected,
however, on the Highway 47 corridor with the arrival
of new residents and requisite housing, roads,
businesses, and support services (Figure 21-8).

Bear River Watershed Comprehensive Lake Management Plan
Figure 21-7. Secchi Depth, Total Phosphorus, and Chlorophyll a Trends for White Sand Lake
Figure 21-8. Phosphorus Loading Sources for White Sand Lake
Future amounts of phosphorus for White Sand Lake
can be anticipated by using a tool (Wisconsin Lake
Modeling Suite - WiLMS) designed to predict
phosphorus levels based on changes of land use in
the watershed (Figure 21-9).
Use of the WiLMS tool reveals that high and medium
disturbance areas characterized by the presence of
roads, homes, buildings, parking areas, and lawns,
yield the most total phosphorus per unit area.
Forested and wetland areas contribute less total
phosphorus as the runoff is slowed and allowed to
seep into the ground instead of washing into the lake
transporting sediment and phosphorus.
Figure 21-9. White Sand Lake Watershed Land Uses (Red – Developed; Blue – Open Water; Light Green – Wetland; Dark Green – Forest)
Habitat Category Habitat refers to a specific place that is inhabited by
a particular organism. Habitat includes all that the
organism needs to live, including physical factors
such as soil, temperature, light; and biotic factors,
such as the availability of food and shelter from
predators. The Habitat category includes substrate
(rock, sand, muck); aquatic plants; riparian zone
(shoreline); and littoral zone (shallow water along
shoreline).
Substrates are the surfaces on which organisms
grow, and rock, sand, and muck are the primary
substrates of a lake. Figure 21-10 shows the
distribution of White Sand Lake’s substrates.
Substrates often indicates the type of plants that will
grow in an area. The diversity of White Sand Lake’s
substrates is important to the health of the lake’s
fishery.

Aquatic plants (macrophytes) are plants that grow in
the water either submerged (all under water),
emergent (sticking out of the water), or floating leaf.
The north end of White Sand Lake has a large area
of dense submerged plants with the most
predominant being fern pondweed.
The Tribal Natural Resources Department assessed
the aquatic plants in White Sand Lake in 2010 by
following the Wisconsin Department of Natural
Resources Protocol for conducting an aquatic plant
point intercept survey (see Section 8).
Table 21-7 presents the statistics associated with
the point intercept survey, and Figure 21-11 shows
plant locations and additional data. The table shows
that of the 681 sites sampled, vegetation was found
at 232 sites and 461 sites were shallower than the
maximum depth of plants, 20 feet. The total number
of plant species found (Taxonomic Richness -
Frequency of Occurrence) was 32 plants, and the
Simpson Diversity Index was 0.91. (See Section 8
for detailed explanations of the terms).
•••• Frequency of occurrence is an estimate of how
often a particular plant species is likely to be
found within a lake. The estimate is based on an
analysis of the data collected during the point
intercept survey.
•••• Simpson’s Diversity Index is a measure of how
diverse a plant community is in the lake. The index
is within a range of 0 to 1. The higher the value, the
more diverse the plant community is in a particular
lake. Plant diversity is an indicator of the lake’s
overall resiliency. Generally, a lake with high
species diversity is considered to be more stable
than a lake with low species diversity because it
has a greater ability to withstand environmental
fluctuations. A lake with a diverse plant community
is better equipped to compete with exotic
infestations than is a lake with low diversity.

Table 21-8 lists the aquatic plants found in White
Sand Lake and shows the Floristic Quality Index
(FQI) for the lake. The FQI is the extent to which a
lake’s plant community is similar to that of a pristine
or undisturbed lake. The higher the floristic quality
index, the closer a lake is to an undisturbed system.
FQI is used to determine whether a lake’s plant
community is changing over time. It is also used to
determine the extent to which a lake’s plant
community is similar to other lakes in the same
ecoregion. The Floristic Quality Index for White Sand
Lake was 34.5, meaning most of the plants can
tolerate moderate disturbances (see Section 8).
Littoral Zone Habitat The littoral zone extends along the shoreline from
the water’s edge into the water to a depth of about
20 feet for White Sand Lake. This is the area where
most of the aquatic plants grow, providing shelter for
fish to reproduce and protect their young. The plants
also reduce erosion caused by waves, stabilizing the
shoreline.
To help determine the extent of residents’
perceptions of aquatic plants, the survey asked
residents if their enjoyment of the lakes was
impeded by the presence of aquatic plants in the
littoral zone. Table 21-9 shows that 45% of 98
residents from White Sand Lake indicate never,
39% rarely, 15% sometimes, 1% often, and 0%
always. When comparing the data for White Sand
Lake with the data for the other lakes, it appears that
aquatic plants are perceived to be somewhat of a
less impediment.
Residents were asked if they or members of their
households have tried to control aquatic plant
growth by removing plants from the lake. Table
21-10 shows that 85% of 94 respondents for White
Sand Lake indicate never, 12% some years, and 3%
yearly.
Residents were also asked if they or members of
their household have removed trees that have fallen
into White Sand Lake. Table 21-11 shows that 62%
of 95 respondents indicate never, 37% some years,
and 1% every year. The data for the respondents of
White Sand Lake are very similar to the data to the
other lakes. They rarely remove trees that have
fallen into the lake.
Residents were asked whether there is a need to
control aquatic plants for White Sand Lake. Table
21-12 shows that 10% of 94 respondents indicate
definitely no, 28% probably no, 22% probably yes,
and 7% definitely yes. Thirty-three percent indicate
they are not sure.
Residents were asked what should be done if an
aquatic invasive plant is found in the lake. Table
21-13 shows that for 34 respondents for White Sand
Lake, 24% indicate remove with chemicals, 24%
remove mechanically, 32% remove with biological
control, 50% remove by hand, 0% do nothing/no
treatment, and 41% indicate they need more
information. When considering the data for all
methods and lakes, it is evident that respondents
seem most comfortable with removing aquatic plants
by hand, and they want more information on the
topic.

Riparian Zone Habitat The riparian zone is the land area along the
shoreline from the water’s edge inland. In general
this area is where most people access the lake via
stairs or paths. It sometimes includes boathouses,
storage sheds, homes, lawns, and other structures.
The riparian zone contributes the most nutrients
from erosion, fertilizers, septic systems, and general
habitat runoff. The area is critical in providing woody
for fish and leaf material for invertebrates, like the
dragon fly which lives a life cycle requiring both
water and land. It is also critical in providing habitat
to sustain other animals that rely on the lakes, like
song birds, eagles, loons, otter, deer, along with a
multitude of other creatures. A poor riparian habitat
often results in fewer species and excess nutrients,
while a good riparian habitat is replete with abundant
wildlife and healthy levels of nutrients.
To help determine the extent of residents’
perceptions of the riparian zone, the community
survey asked residents to describe the landscape in
the 35 foot buffer between the shoreline and their
house, and to identify what they believe should be in
an ideal landscape for the same area.
Table 21-14 lists several landscape features
ordinarily found in riparian zones. Residents were
asked to check those features that characterize the
Section 21: About White Sand Lake 21-15
Bear River Watershed Comprehensive Lake Management Plan
current riparian landscape (Current) for their
property and then check those features that they
believe should be in an ideal riparian landscape
(Ideal). The table compares residents’ descriptions
of the current landscape with their perceptions of an
ideal landscape. For example, 34% of respondents
affiliated with White Sand Lake identify mowed grass
as a feature of the current buffer zone for their
property, yet 25% of them identify mowed grass in
an ideal landscape.

The current primary features identified by all three
respondent groups include mowed grass, wild,

landscape, the same respondents prefer landscapes
characterized by less mowed grass and less wild
with fewer trees and shrubs, but more sand beach.
Residents were asked if they are interested in
learning about landscape designs tailored to help
protect the lakes and habitats. Table 21-15 shows
that of 89 respondents for White Sand Lake, 5%
indicate no interest, 37% little interest, 2% some
interest, 10% a lot of interest, and 46% don’t know.

Assessment of Riparian & Littoral Zones The Habitat Category reflects an assessment of
White Sand Lake’s aquatic plants, riparian zone
(shoreline), and littoral zone (shallow water along
shoreline). Comparisons are made with ecoregional
data, National Lake Survey thresholds and
WISCALM (Table 10-4).
Riparian cover includes cover-class estimates of
large and small diameter tree cover in the >5m high
vegetation layer; woody and non-woody vegetation
in the mid-layer (0.5 to 5 m); and woody, non-woody,
inundated, and barren classes in the ground cover
layer (<0.5 m) of the 10 lakeshore plots. Littoral
cover index excludes submerged aquatic
macrophytes, but increases the weighting of floating
and emergent macrophytes.
Table 21-16 compares the thresholds developed by
WISCALM for Plants and the National Lake Survey
for Riparian Zone and Littoral Zone to the index
value calculated based on the assessment of White
Sand Lake's habitat.

To help learn about residents’ perceptions on habitat
and environmental change, the community survey
asked residents if elements of the habitat have been
changing over time. Table 21-17 shows the
responses for White Sand Lake, the Bear project
lakes, and the other lakes. The data are very similar
for all three response groups. The predominant
response is no change.
Bacteria Category Bacteria is assessed based on a measure of the
most probable number (MPN) of E. coli in 100
milliliters of water. E. coli is the abbreviated name of
the bacterium in the family Enterobacteriaceae,
named Escherichia coli. The presence of E. coli in
our intestines is normal. The presence of E. coli in
swimming areas indicates that other microorganisms
(including the ones that could causes illness) that
live in the gastrointestinal track could also be
present. The water quality criterion to protect human
health, 235 MPN, is based on an illness rate of eight
per 1,000 swimmers. White Sand Lake does not
have a public swimming beach so bacteria is not
assessed for White Sand Lake.
Generally, the Tribe is responsible for septic
systems on property owned by the Tribe, and Vilas
County is responsible for septic systems on property
on non-Tribal land. Currently, all septic systems

Residents were asked how often they have their
septic tank inspected. Table 21-18 shows that for 63
respondents of White Sand Lake, 0% indicate they
do not own the property, 86% at least every three
years, 0% no septic tank, 10% more than every

Aesthetics Category The Aesthetics Category includes data and
information on water quality, color, and turbidity. It
also reflects an assessment of reports received by
the Tribal Natural Resources Department for White
Sand Lake on the presence of oil, grease, nuisance
aquatic plants, trash, and debris.
Reports and concerns submitted by residents to the
Tribal Natural Resources Department on the turbidity
and color of the lake water are not uncommon.
The extent to which lake water appears to be clear
or murky is a function of the total amount of solids
that are suspended in the water. Generally, the
greater the amount of suspended solids in the water,
the murkier it appears.
The major source of turbidity in open water away
from shore is typically phytoplankton (algae). Closer
to shore, suspended matter also comes from
sources such as septic systems, sewage treatment
plants, storm runoff, shoreline erosion and lake
bottom sediments.
The major effect of turbidity noticed by lake property
residents might simply be aesthetic - people do not
like to look at dirty water. High levels of turbidity can,
however, cause major problems by inhibiting the
penetration of light, leading to the suffocation of
larvae, damage to fish gills, fish reproduction, and
loss of aquatic plants and habitat.
Turbidity or cloudy water can be measured in a
variety of ways. A method commonly used in Lac du
Flambeau to measure water clarity is to employ a
Secchi disk. The 8-inch diameter disk with white and
black quadrants is tied to a line and lowered slowly
down into the water. The depth at which the white
quadrants are no longer visible is taken as a
measure of the transparency of the water. This
information provides a way to look at changes in
water clarity over a long period of time. Secchi data
also correlates to total phosphorus and trophic state
index data. Figure 21-12 shows that over the past
22 years no significant change in water clarity has
occurred for White Sand Lake.
21-18 Section 21: About White Sand Lake
Bear River Watershed Comprehensive Lake Management Plan
The color of lake water reflects the type and amount
of dissolved organic chemicals it contains.
Transparent water with a low accumulation of
dissolved materials appears blue and indicates low
productivity. Dissolved organic matter, such as
humus, peat or decaying plant matter, can produce
a yellow or brown color. Some algae produce a
reddish or deep yellow color. Water rich in
phytoplankton and other algae usually appears
green.
Volunteers for White Sand Lake have been
subjectively observing and recording the lake’s
water color since 1995 as part of the WDNR’s
Citizen Lake Monitoring Network. Table 21-19
summarizes the observations for the North location
and Table 21-20 for the Deep Hole location. The
numbers preceding the colors indicate the number of
dates of observation. For the North location, blue
was recorded 19 times, green 5 times, and brown 1
time. For the Deep Hole location (Table 21-20), blue
was recorded 23 times, green 12 times, and brown 1
time. The specific dates of the observations are
available on the Citizen Lake Monitoring website at
http://dnr.wi.gov/lakes/clmn/. The website also
shows that despite the variations in water color, the
observers reported that, with very few exceptions,
the water appeared to be clear as opposed to
murky.

In order to learn about residents’ perceptions of the
lake water quality, the community survey posed a
few questions about water quality. Residents were
asked to describe the current water quality of White
Sand Lake and whether they believe that quality has
been changing.
Table 21-21 shows that 57% of 100 respondents for
White Sand Lake indicate that the current water
quality of the lake is excellent, 42% good, 1% fair,
0% poor, 0% very poor, and 0% are unsure.
Respondents have a very positive perception about
the current quality of White Sand Lake’s water.

The data for White Sand Lake regarding perceptions
of current water quality are reasonably consistent
with the data for the other lakes identified in the
table. Table 21-22 shows that 1% of 95 respondents
for White Sand Lake indicated that water has been
improving, 66% no change, 16% worsening, and
17% are unsure. Again, the data for White Sand
Lake are reasonably consistent with the data for the
other lakes noted in the table.

Fish Tissue Category & Fishery The Fish Tissue Category refers to the amount of
mercury in fish flesh as compared to Water Quality
Standards. Larger edible fish have more mercury in
the fish flesh than what is protective for human
health concerns. Tribal Water Quality Standards are
protective for subsistence fish consumption and the
criterion to protect human health is 0.16 PPM.
Anthropogenic (meaning caused by human activity)
sources of mercury are mainly from coal fired
electric utilities emissions that ultimately enter the
lake and watershed via rainwater. The chemistry of
Lac du Flambeau Lakes is such that mercury
becomes mobilized into the food chain accumulating
in larger fish at the top of the food chain. Reductions
in mercury emissions on coal fired power plants
have helped to reduce mercury in the rain as seen in
Figure 21-13. A comparison of 1991 data to 2007
data shows a trend of reduction, yet more than what
is protective for human health.
21-20 Section 21: About White Sand Lake
Bear River Watershed Comprehensive Lake Management Plan
Figure 21-13. Mercury Fish Tissue Concentrations vs Fish Length
White Sand Lake’s fishery supports both
subsistence and sport fishing. The lake’s fishery
includes panfish such as bluegill and black crappie
and gamefish like smallmouth and largemouth bass,
northern pike, musky, and walleye. The lake also
includes lake sturgeon.
The Tribal Hatchery has a history of stocking White
Sand Lake, particularly with walleye, musky, and
sturgeon. Table 21-23 shows the numbers of these

In order to determine residents’ perceptions on the
quality of fishing and whether that quality has been
changing, this survey asked residents a few questions
about the fishery. Residents were asked if they have
fished or speared on White Sand Lake within the past
ten years. Seventy-six of 102 (75%) respondents for
White Sand Lake responded affirmatively.
These respondents were then asked to identify the
type of fishing they employed. Of those who
responded, 96% indicate open water hook and line
fishing, 24% ice fishing, 0% spearing, and 0% netting.
The residents who have fished or speared within the
past ten years were asked to describe the current
quality of fishing on the lake, and how, if at all, the
quality of fishing on the lake has changed during the
past ten years.
Table 21-24 shows that of the 71 White Sand Lake
residents who responded about the current quality of
fishing, 1% indicate excellent, 25% good, 52% fair,
11% poor, and 9% very poor. One percent indicates
unsure. A higher percentage of respondents for
White Sand Lake indicate the current quality of
fishing is fair to good as compared to respondents of
the other lakes.

Lake Water Levels Lake levels fluctuate naturally due to precipitation
and evaporation, both of which may vary widely from
season to season and year to year. Low levels may
cause stressful conditions for fish and increase the
number of nuisance aquatic plants. High water
levels can boost the amounts of nutrients from runoff
of flooded lakeshore soils. Another consequence of
fluctuating water levels is shoreline erosion.
White Sand Lake is artificially stabilized by a static
dam on the out flow at the beginning of Hutton’s
Creek.
Figure 21-14. Lake Water Level Fluctuations During 2012-2014
Volunteers from Lac du Flambeau have been
subjectively observing and noting lake water levels
through the WDNR’s Citizen Lake Monitoring
Network for many years (Tables 21-26 and 21-27),
while in 2012 the Tribal Natural Resources
Department began to collect water level data
systematically for selected lakes. With assistance from
North Lakeland Discovery Center, Vilas County
Association of Lakes, and Town Lakes Committee,
monitoring equipment was installed and calibrated
on sites at Little Crawling Stone Lake, Fence Lake,
Flambeau Lake, Ike Walton Lake, and White Sand
Lake (Figure 21-14). The equipment at the Flambeau
Lake site is being monitored by the Tribal Resources
Department while equipment at the other sites is being
monitored by volunteer lakefront property owners.

White Sand Lake Association32 Volunteer organizations in Wisconsin have long
played an important role in protecting the lakes from
declining water quality and other human impacts. To
address such issues, residents on Lake Geneva
established the first lake association in Wisconsin
1898.
In July, 2004, 76 residents representing about 50
families on White Sand Lake decided to establish
their own lake association at a meeting held at
Dillman's Resort. Education and communication
were identified as the new organization's primary
purposes.
The following June, the association held its first
business meeting, again at Dillman's. A Board of
Directors and officers were identified, by-laws were
adopted, and dues were set at $20 per family.
A resident from White Sand Lake and member on the original
planning committee for the White Sand Lake Association, John
Bartosz, was instrumental in establishing the Lac du Flambeau
Town Lakes Committee, indeed serving as the organization's
first chair. The White Sand Lake Association has been
represented on the Lac du Flambeau Town Lakes Committee
since its inception in 2005.
Several lake association members have attended various training
sessions conducted by the Lac du Flambeau Town Lakes
Committee and help monitor the public boat landing and
21-24 Section 21: About White Sand Lake
Bear River Watershed Comprehensive Lake Management Plan
shorelines for AIS, testing for and reporting on water quality,
depth, and lake water levels each season.
Several association members assisted in the survey of the aquatic
plant life of White Sand Lake in preparation of the Bear River
Comprehensive Lake Management Plan.
Relying in part on WDNR grant funds, the White Sand lake
Association hired watercraft inspector in 2014.
Setting the Pace & White Sand Lake In summary, White Sand Lake has a very healthy
ecosystem with many strong qualities. The primary
challenge is ensure these attributes do not degrade
from their current conditions. At the same time, there
is room for improvement, particularly with respect to
improving the lake’s habitat, monitoring the
presence of mercury in fish tissue, and guarding
against the arrival of aquatic invasive species.
The following tables, Setting the Pace, constitute a
long-term action plan to maintain or improve the
overall health of White Sand Lake. The plan includes
six goals with supporting objectives and activities.
The goals include:
I. Preserve or Improve Current Water Quality.
II. Prevent Infestations of Aquatic Invasive
Species.
III. Control or Reduce the Spread of Aquatic
Invasive Species.
IV. Broaden Residents' Understanding of
Swimmer's Itch.
V. Reduce User Conflicts.
VI. Strengthen or Increase Collaborations.

14. Goc, 92. Additionally, the following statement was provided by Hoyt Bacon, son of William Thompson Bacon, Jr., an early supporter and owner of the camp. Camp Wipigaki was founded in 1922 by ten Chicago families. Today, the majority of the original families still retain an interest in the Camp, which is now owned by 12 families. The vision was to create a communal family camp retaining as much as possible of the natural environmenrt in the woods and lakes. Over the years the camp has acquired more land and today has land adjoining seven lakes - White Sand, Little Sand, Eagle, Ike Walton, Pokegama, Sunfish and Crooked. The Camp is in the State of Wisconsin's Managed Forest Plan and has harvested the forests according to the plan. There are no plans for any more development on the land or to sell any portion of the land the Camp owns. (Hoyt Bacon, 2014).
